CONTAINER AND IMHOD 01' PRODUCING SHE.

Application filed Kay 28,

To all whom i!- may concern:

lie it known that l, JHNATIIAN Pn'rnnsoN. a citizen of the United States, residin at Brooklyn. in the county of Kings and bta-te of New York. have invented new and useful Improvementsin Containers and Methods of Producing Same, of which the following is a specification.

This invention relates to the production of receptacles, such for instance, as boxes. pouches or containers, pertaining more particularly to the production of structures of this general character especially adapted for use as receptacles for manufactured products of a perishable nature, such. for instance as are affected by atmospheric changes, an example of which may be found in the various kinds of tobacco products.

The receptacle of the present invention carries many of the characteristics of structures shown in prior patents granted to me for this general purpose, such prior receptacles being formed from a composite sheet made up of a plurality of plies united together by an interposed film of cementitious material-such as a rubber compound-a sheet of this type being disclosed in the patent granted to me February 27th, 1917. #1211820. Receptacles made from such sheet formation carry certain desirable qualities, some of which are the pliable or flexible nature of the receptacle and the air and moisture proof characteristics of the sheet.

In the formation of the receptacle from such sheets, however, it is more or less essential that additional elements be employed,

especially where the package is of the closed-end type--produced by doublin the sheetupon itself in the formation of the package. For instance, in the patent referred to the sides of the receptacle are closed by an additional binding strip applied externally for the purpose of closing the points of meeting of the doubled portions of the sheet, thus necessitating the use of vadditional strips in closing the side seams of the receptacle.

In the present invention, this closing of the side seams is effected during the production of the container and the composite sheet structure from which the container is formed, thus not only eliminating the necessity for the use of the additional binding Specification of Letters Patent.

strips, but. in addition, producing a seam structure as a art of the composite.formation itself. is a result, the flexibility or pliability of the receptacle is maintained and at the same time the re ceptacle manufacture is provided in such form as to insure the air and moisture-proof character of the seam formations.

To these and other ends, therefore, the nature of which will be readily understood as the invention is hereinafter fully disclosed, said invention consists in the improved receptacle and the methods of manufacture of the same, hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the accompanying drawings, in which similar reference characters represent similar parts in each of the views, Figs. 1 to 3 inclusive are perspective views showing stages in the formation of the inner ply, element or embryo formation of the composite structure.

Figures 4 to 6 inclusive are similar views showing stages of applying the outer ply elements to the embryo formation.

Figure '7 is a perspective view of a complete receptacle.

Figures 8 and 9 are transverse sectional views taken on lines 8-8 and 9-9 of Figure 7.

The production of a these general characteristics is made possible through the use of a. cementitious material of the general character pointed out in the said identified patent-a' material which has cohesive qualities under certain conditions and retains its pliability or flexibility when the structure is completed-different in this respect from the effects of the use of the usual adhesive material, such for instance as glue; as will be understood, the usual adhesive, when set and dried, becomes hard and is more or less brittle, so that the walls of the receptacle are more or less stiff, so that distortion of the receptacle tends to crack or. otherwise break down the integrity of the connection between the plies or elements.

In use the cementitious material is applied to adjacent sheets or ply faces whicli areto be brought into direct contact in the formation of the receptacle structure, the contacting faces so conditioned being united, the comosite sheet or wall effect being produced y such uniting action.

In the present method of producing a receptacle, I employ an element a and an element b; these may be of suitable contour, but are preferably of a substantial uniform width, greater than the COITQSPOIldlUi dimension of the completed receptacle. ach'. of these elements has one of its faces coated with the cementitions material, and since one of the characteristics of this material is that where applied as a simple coating, it ma become dry without losing its ability to facially united with another face similarl coated the individual elements can be ily handled for the purpose.

In practicin the present invention element a is folde into a closed-end cup formation, as shown for instance in Figs. 1 to 3 of the drawin The folding may be provided on a suitab e form, the element being so applied that its uncoated face will be out of contact with the formthe coated side being located on the exterior face of the embryo formation. The form indicated at 0, may be of suitable type, as for instance a block of the desired size and contour; the part of an automatic machine, such as a plunger for instance; or, where the receptacle is to receive a commodity such, for instance, as plug tfob'acco, the plug itself may constitute the As shown in Figs. 1 to 3, the element is first located on the form with the element folded or doubled as in Fig. 1, to provide the closed end a, after which the excess element material at the op osite sides of such end is tucked inas in ig. -2to provide wing formations a at the sides of the front and rear faces of the folded elements; these wings or wing formations are then folded laterally into overlapping or over-la ing relation, as in Fig. 3. It will be un erstood that a form or its equivalent is employed throughout the development of the receptacle, Figs. 2 to 6, omitting the form for purposes of clearness in showing.

While the cementitious coating is present on one of the contacting faces of wings a, such faces are generally not connected to- .gether, owing to the fact that the cementitious material, after drying, does not readily adhere to an uncoated sheet surface, so that in the formation of Fig. 3 the block or element is simply in folded condition with the exception that in producing wings a certain coated faces are brought into contact through the particular formation of the tuck-in at the closed end with the result that such latter faces may have an adhering or coherin relation, tending to maintain the genera embryo formation at this stage.

Owing tothe fact that the coated face of the blank or element (1 forms the exposed face of the embryo formation of Fig. 3 it will be understood that with the exception of the open end of the formation, each face of the latter presents an exterior coated surface, with the sides or edges having the face formed from wings which extend in opposite directions. In the presence of these conditions, element 1) is a plied, this element being substantially simi ar to element a, but in its application, the coated face of the element forms the inner face.

While element b may be applied in any suitable formation and by any suitable means, I prefer to apply it by a formation similar in character to that of the foldin of element a, as shown in Figs. 4 to 6, t ese views corresponding more orless to the stage views of Figs. 1 to 3, the difference bein in the location of the coated faces and the act that while element a is folded directly on to the form, this folded formation of element a serves as a portion of the form itself during the fold'in of element b.

When, t erefore, the opposing coated faces of the two elements are brought into contact, the conditions for uniting the two elements into acom osite formation are produced, the severa walls of the receptacles having the characteristics of a receptacle formed from the composite sheet of the patent referred to, but carrying certain important distinctions as will be understood from the following: While the front and rear faces as well as the closed end-correspond-' ing to a section taken longitudinally of the receptacle-are similar to the composite sheet formation of the patent, the formations at the sides-the formations produced by the -wingsmaterially differ. For instance, in folding elements a, the production of the tuck-inof Fig. 2, brings uncoated faces into contact-see the triangular formations a of Fig. 2; but when wings a are folded the coated faces of these parts a are brought into contact with the coated faces of the infolded excess ends a, thus sealing the folds at this int-an arrangement due to the fact that t e coated side of element a is external when folded. When the element 12 is iven a similar fold, however, the productlon of the triangular formations b by the infolding of the excess ends 12, brings opposing coated faces into contact-parts b with wings b -th'us producing the seal at this point and before the wings receive their lateral folding; at the same time the production of the infold 6 places its coated face in contact with the coated faces of wings a and the exposed portion of infold (1, thus providing the seal at this point. And a similar action is provided in connection with wings I), the first folded wing bringing its coated face into contact with the coated faces of wings a, the last folded wing b bringi its coated face into contact with the coated ace of that wing of the wings a whichhas not been coated by the first folded wing b. This leaves a part of the coated face of the last folded wing I) in opposition to an uncoated face, and to avoid the provision of a loose portion at this point, a strip of adhesive is preferably applied either to the edge of such coated face or on the uncoated face of the first folded wing-preferably the former as shown in the drawings-thus producing an ordinary adhesive connection at the edges of the last folded wings L This completes the receptacle formation, and as will be understood all joints, crevices and seams are sealed by the cementitious connection and at the same time the conditions of a composite sheet formation are bad with the sides of the package having a seamlike connection bearing the characteristics of the composite sheet in that the air and moisture proof conditions are produced without sacrificing the pliability or flexibility of the receptacle formations and without the use of the additional binding strips of the prior patent.

As will be understood the particular methods employed are such as to practically produce a nested relation between the two elements each of which is folded individually, and in which each element has folded portions individually united in addition to the uniting of the opposing faces of the nested elements.

The elements a and b may be of suitable material, as for instance paper sheets and mayahave any desired characteristics. For instance, element a may be of the type which presents a prepared face on one side and the cementitiously-coated face oni the other, the prepared face being, for instance, of the paraifine type, a form of sheet made possible by the fact that the cementitious coating does not penetrate the prevent more or less impregnation sheet itself by the parafiine, the cementitious coating, however, serving as a barrier to pre vent the paraffine from reaching the opposite or outer sheet. Similarly, element 6 may be of a single sheet-which may practically constitute the label for the packageor may be formed of a composite sheet structure as may be found most desirable. The general essential is that the two elements should have that face which opposes the face of the other element provided with the cementitious coating, the two coatings combinedly producing a film-like formation between the elements such as gives the adof the hesive results accruing from the composite sheet of the prior patent.

The present invention is not restricted to any form of apparatus for practicing the method of producing the receptacle, it being understood that the productlon may be by hand orby the use of apparatus, and the sheet fibre sufficiently toform of thelatter. may vary as may )be found most convenient,

While I have hereinsh'own and described one form in which the invention may be practised and of a by, it will be readily understood that in meeting the various exigencies of useand in producing, receptacles for the different purposes for which it may be employed, changes and modifications therein may be found desirable or necessary; and I desire to he understood as reserving the right to make any and all such changes or modifications as may be found desirable or essential in so far as the same may fall within the spirit and scope of the invention as expressed in the accompanying claims when broadly construed.

Having thus described my invention, what 1 claim as new, is:

1. The method of providing a pouch-like multi-walled receptacle which consists in wrapping a pouch-forming member having on its interior a normally dry cementitious material onto another similar member having on its exterior a similar material.

2. The method of producing apouch-like multi-walled. moisture proof receptacle which consists in folding a blank coated on one side with normally dry cementitious material into receptacle form, then wrapping there-around another similar blank so that the coated surfaces will adhere in a way to make the receptacle moisture proof.

3. The method of producing a water proof double wall receptacle which consists in applying a binding material over the outer face of the inner wall, folding the bottom, then the sides of the inner wall to form a pouch-like receptacle, then covering the in ner wall by a similarly interiorly coated and folded outer wall.

4. The method of producing a double wall receptacle which consists of applying a binding material to the outer surface of the inner and the inner surface of the outer wall, folding the bottom, then overlapping the sides of the inner wall and similarly closely folding the outer wall around the inner wall and with the inner fold of the outer wall over lapping the outer fold of the inner wall.

5. The method of producing a water-proof double wall box-like receptacle which consists in applying an adhesive tothe meetin surfaces of the walls folding in the bottom and sides of the inner wall so the sides and the bottom will overlap to form the ends similarly folding the outer wall around the inner wall with the overlapping ends of the outer wall breaking joints with those of the inner wall.

6. A multi-walled receptacle comprising two separable receptacles one having cementitious material on its exterior and snugly nested into the other having cementitious material applied on its interior, the surfaces product prmluced there-- adhering only where a coated surface contacts with another coated surface whereby the receptacles may be manipulated while dr and afterwards caused to adhere while stil in a dry condition.

7. A multi-walled receptacle comprising an outer receptacle inwardly coated with a cementitious material, the receptacle having sides, a continuous bottom and folded ends, 10 a similar inner receptacle outwardly coated,

the inner fold of the outer receptacle overlapping those of the inner receptacle whereby the folds may be separately made while dr and afterwards caused to adhere while 15 sti 1 dry.

8. A receptacle of the closed end type formed of two substantially rectangular sheets each folded separately into elements having wing structures, said elements being nested together and united b a normally dry cementitious material on t eir o posing faces, with a wing of the outer fold ment united to a pair of wings of the inner folded element the inner element having portions in united relation independent of the outer element.

In testimony whereof I have hereunto set my hand.
